I have a Windows 10 machine that used to work just fine. Now when you do a reboot the password box and text does not show. You can type the password and get enter and it will work.

What would cause the machine to no longer show the password box on bootup or accept a recovery usb key and skip needing a password?

  • This is the third question to be asked about this behavior. It sounds like a common update is causing the problem. The rest of the users with this question, never really described the problem in any significant detail, nor did they ever try possible soltuion. If you decrypt the system drive, and encrypt it again, does the problem still present itself?

  • @Ramhound I did some searching and I found this: answers.microsoft.com/en-us/windows/forum/windows8_1-security/… -- Go Microsoft again to screw stuff up... This is probably why people are disabling automatic updates.

  • I wasn't being critical of this question. I was making a comment, that this was like the third, Bitlocker password field related question I have seen. I would still try my suggestion.

  • @FrankThornton I'd rather have a full blue screen rather than a bug that allows secure boot to be bypassed.

The fix here worked for me:

  • Open a CMD session as Admin

  • Use the command bfsvc.exe %windir%\boot /v.

  • After a restart, the texts should reappear.

    This fixed the issues for me.

  • @ardaozaki don't accuse people of voting. I removed my comment since you addresses my concerns.

  • @Ramhound you are free to vote as you want, I was just saying that voting without reading is not the best way to vote. I also removed my first 2 comments.

  • I read your answer, the original revision was a little sparse, after having read the link.

  • Worked for me -- the problem was probably arising from our custom deployment system that creates the EFI startup folder on the ESP with a minimal set of files

Same here:

enter image description here

Solved this problem using this answer: http://answers.microsoft.com/en-us/windows/forum/windows8_1-security/bitlocker-pin-pre-boot-screen-empty/f985c4f6-dd71-4586-bd46-50f513432bb3?auth=1

The moment it started talking about fonts I realised - maybe everything is working just fine - just the text isn't displayed.

Type your password as usual and hope Microsoft will update the thing

  • Yep, this was the first thing I tried when debugging first issue. It does work unless your end users are stupid and panic and support calls come in :( But good answer!

Issue is a Windows 10 update.

Removed update and did a rencrypt and it fixed the issue.

Pushing out and blocking the update on over a 1000 machines. Yay for Mondays.

Well, it turns out that a cumulative update for Internet Explorer interferes with the blue bitlocker screen on startup.

Affects various flavours of hardware.

On our blank blue screens, if we type the bitlocker password as normal, you can log in fine.

Its Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3172985) Odd. So, to recap, start your machine. you'll get a blue bitlocker screen - with nothing on it. no text input box, or even text! Type your password in as normal, viola.

Finally after 2 years of waiting and all windows updates i found a good working solution It didn't work (bfsvc.exe %windir%\boot /v) It also didn't work (diskpart select disk 0 select partition 1 assign letter=s: Keep the diskpart window open don't close it yet Open another Admin Command Prompt and overwrite the files in s:\efi\microsoft\boot\fonts with your good Truetype files. Or if you prefer rename the old ones to *.bak and then copy your good files here. Back in the diskpart window remove letter=s:)

But this WORKED (plug in a usb stick example e:, and your disk example c: 1) open cmd in administrative rights 2) type: manage-bde -protectors -add c: -recoverykey e: so this saves a key to your thumb drive when restart you will see a normal screen with text! if you want to add or remove password or recoverykey use the same command example manage-bde -protectors -delete c: -password

the commands somehow corrects all text but you can do it also in another way . by rightclick on disk> manage bitlocker> turn off then enable again but don't give password. just use a usbdrive to save the key then use command to add password if you want! see your protectors with the command: manage-bde -status there you can see the protectors used as: password, recoverykey ecc
